About the Project:
The project "ClearWater" focuses on employing a photocatalytic approach for the complete decomposition of soluble water contaminants into non-toxic molecules, using a photocatalyst developed and patented at TU Berlin. Laboratory-scale demonstrations have already showcased the effectiveness of this approach, revealing its capability to decompose various anthropogenic trace substances using visible light in the presence of a suitable oxidizing agent. The results show that the photocatalytic approach is a far more efficient alternative to established methods. Through funding from VIP+, the project aims to realize a demonstrator in collaboration with industry and public sector partners. This demonstrator will facilitate market-oriented validation, marking a significant milestone toward commercialization.
The project also involves close cooperation with numerous project partners and stakeholders. Therefore, a structured approach to work, as well as the documentation and presentation of results, are important cornerstones for successful collaboration. Additionally, the role encompasses diverse responsibilities, including internal communication, organizing and facilitating project meetings, compiling and delivering presentations, coordinating workshops, and representing the project at conferences. The successful candidate will take the lead in project outcomes within the framework of scientific exploitation.

What we are aiming for:
As part of extensive decomposition experiments on a laboratory scale, the photocatalyst was tested for its reactivity and efficiency in the photocatalytic decomposition of various classes of pollutants in aqueous solution using visible and sunlight, and an oxidizing agent. The compounds under investigation (e.g., pharmaceutical residues, hormones, steroids, biomolecules, synthetic nitriles, benzene, polymer compounds, dyes, and fluorinated compounds) are currently often only partially or not at all removed from wastewater and accumulate in our water treatment cycle. The goal is to further develop the technology into a demonstrator that complements and optimizes traditional methods as a fourth cleaning stage. To realize a demonstrator capable of decomposing larger volume flows, a variety of work is required. This includes investigations into the scope of application (screening), catalyst stability, reaction management, and optimization, as well as the synthesis of the catalyst on a larger scale. In addition to chemical expertise, an engineer will also be involved in the project, who will deal with the design, construction, building, and commissioning of the demonstrator. In extensive field tests, this will be technologically evaluated in collaboration with partners. This also includes assessing potential applications, economic viability, and environmental compatibility. Finally, a strategy for technology transfer should be developed.

With "ClearWater," you are part of an exciting technological development in the field of wastewater treatment.


We are looking for a scientist with a completed scientific university degree (Master, Diploma, or equivalent) in the field of chemistry/process engineering/chemical engineering or a comparable relevant field of research with a completed doctorate, specializing in catalysis, kinetics, and reaction engineering, as well as in-depth expertise in heterogeneous catalysis, kinetic studies, reactor design, and reactor construction.
Very good knowledge of German and/or English is required or the willingness to acquire the missing language skills.

Experience in the development and application of novel technologies and processes for wastewater treatment is desirable. Theoretical and practical knowledge in the area of photocatalysis and the development of reaction systems (reaction and separation processes) for the implementation of large-scale processes are also advantageous.
Furthermore, you are expected to work independently and creatively, enjoy new challenges, be a team player, and have good social skills.
